Narrative:

When I departed, the tower was closed but the winds were calm so I taxied to runway 13L for takeoff. I monitored the CTAF frequency of 121.0 throughout my taxi and heard nothing except for a helicopter landing on the ramp. As I pulled out onto the runway for takeoff, I announced my intentions on 121.0, turned on my landing lights, and advanced power. After reaching 40-50 KTS, I observed landing lights at the far end of the runway apparently coming toward me. I aborted my takeoff and announced that fact on 121.0. I then observed the conflicting traffic turn off the runway. Adequate runway remained so I again announced my intentions on 121.0 and successfully departed from that point. As I flew past the approach end of 31R, I observed a commuter aircraft holding short of the runway. I discussed the incident with that aircraft on 121.0. He had taxied onto 31L for takeoff, had seen my landing lights, and had immediately cleared the runway. I do not understand why neither of us heard the other preparing for takeoff unless our transmissions blocked each other out. I wear a headset in my aircraft and have no problem with radio reception. I am convinced that the use of landing lights for takeoff on both our parts allowed us each to see that a potentially catastrophic situation was developing and to take appropriate actions.

Title: 2 ACFT ENTER OPPOSITE ENDS OF THE SAME RWY FOR TKOF AT NIGHT.

Narrative: WHEN I DEPARTED, THE TWR WAS CLOSED BUT THE WINDS WERE CALM SO I TAXIED TO RWY 13L FOR TKOF. I MONITORED THE CTAF FREQ OF 121.0 THROUGHOUT MY TAXI AND HEARD NOTHING EXCEPT FOR A HELI LNDG ON THE RAMP. AS I PULLED OUT ONTO THE RWY FOR TKOF, I ANNOUNCED MY INTENTIONS ON 121.0, TURNED ON MY LNDG LIGHTS, AND ADVANCED PWR. AFTER REACHING 40-50 KTS, I OBSERVED LNDG LIGHTS AT THE FAR END OF THE RWY APPARENTLY COMING TOWARD ME. I ABORTED MY TKOF AND ANNOUNCED THAT FACT ON 121.0. I THEN OBSERVED THE CONFLICTING TFC TURN OFF THE RWY. ADEQUATE RWY REMAINED SO I AGAIN ANNOUNCED MY INTENTIONS ON 121.0 AND SUCCESSFULLY DEPARTED FROM THAT POINT. AS I FLEW PAST THE APCH END OF 31R, I OBSERVED A COMMUTER ACFT HOLDING SHORT OF THE RWY. I DISCUSSED THE INCIDENT WITH THAT ACFT ON 121.0. HE HAD TAXIED ONTO 31L FOR TKOF, HAD SEEN MY LNDG LIGHTS, AND HAD IMMEDIATELY CLRED THE RWY. I DO NOT UNDERSTAND WHY NEITHER OF US HEARD THE OTHER PREPARING FOR TKOF UNLESS OUR TRANSMISSIONS BLOCKED EACH OTHER OUT. I WEAR A HEADSET IN MY ACFT AND HAVE NO PROBLEM WITH RADIO RECEPTION. I AM CONVINCED THAT THE USE OF LNDG LIGHTS FOR TKOF ON BOTH OUR PARTS ALLOWED US EACH TO SEE THAT A POTENTIALLY CATASTROPHIC SITUATION WAS DEVELOPING AND TO TAKE APPROPRIATE ACTIONS.
